Modern medicine has risen to a previously unattainable level over the past decade. Simultaneously one of the main directions in the Internet of things is the development of medicine and public health. Within the health care system, the issue of monitoring patients, tracking their location and health status (monitoring of temperature, pressure, palpitation and other physical parameters) is especially topical. Due to the development of the Internet of things, the digital transformation in health care is expanding at a high rate. The authors focus on the creation of a special web application for distant high-risk group patient’s heart-rate tracking with a fitness bracelet (fitness tracker). Based on the existing two main approaches for creating web applications the authors determine the effectiveness of bracelet’s use in the health care system for distant high-risk group patients. The results showed that the described method of creating native hybrid applications is the fastest way, perfectly suitable for rapid prototyping and initial launch of the project, however, for a more serious and heavily loaded application, it is worth choosing React Native. Conclusions. This study demonstrates the implementation of IoT and IoMT based on a web application. The application of any approach in public health services should be based on the questions posed to the developer and the medical institution.
